Well, "Pagan" is such a big umbrella... Wicca is certainly one path that falls under the pagan umbrella, but there are plenty of paths that have relatively little in common with wicca. So (for example) a workbook that discussed a duotheistic complimentary Godess/God understanding of the divine might appeal to a Wiccan family, but wouldn't be as applicable to a family in the Church of All Worlds, or an Asatru family, or an Irish Recon family, or a classical Polytheistic family, or (lords and ladies of light save us) an Erisian family.
There's a nice article about wicca vs witch vs pagan on the Reclaiming homepage here
. (disclaimer, I was a member of a Reclaiming group for many years and am still very fond of that path. So I tend to agree more than disagree with their view of the world.)
What I'd like to offer is a more "generally" pagan curriculum... so using terms like vernal equinox or winter solstice instead of ostara or yule (since one is a universal/natural/planetary event while the other is a socio-culturally constructed event that doesn't apply to all pagans). Or starting a study of "american history" with, say, the planet itself and the break up of pangaea/laurasia and then following the progress through the "eyes" of a tree or a squirrel instead of the "eyes" of humanoids crossing the land bridge, or landing in viking long boats, or eventually showing up with columbus or the folks at plymouth. So not really "teaching pagan theology/technique" but instead teaching the various academic subjects from a pagan worldview.
I guess I look at curriculum like Rod & Staff, or A Beka, or Sonlight, or the Noah Plan, or even the Well Trained Mind or Charlotte Mason reading lists, and they have such a strong christian focus.... an assumption of what is important, or what is normal, or a way of looking at the world that comes through in every subject, even those that don't seem "religious" at first glance. So I'd like to offer a full curriculum, that meets state standards and provides a strong academic progression, but where the assumptions and norms and literature selections and examples and projects and crafts are more earth centered/pagan friendly/nature affirmative.
Similar in some ways to the Global Village peace/ecology/justice curriculum where the various subjects are taught from a multicultural perspective.
(oh... different curriculum styles... the Homeschool Diner has a fabulous overview of different philosophies, styles, and curriculums here
. It's a fun site, and worth a browse.)
